Application filed December 6, 1M1. Serial No. 664,808.

To all whom it may concern:

Be it known that I, JosnrH H. McGowan, a citizen of the United States,residing at \Vatha, in the county of Fender and State of North Carolina,have invented certain new and useful improvements in Cultivators, ofwhich the followingis a specifica- Fig. 2 is a side elevation thereof.Fig. 3 is a side elevation of a slightly modified structure. Figs. 4 to6 are diagrammatic views showing the different groupings of the vshovels.

Referring specifically to the drawings, 10 denotes the cultivator beam,the front end of which carries a clevis 11 for attachment of the draftanimal. To the rear end of the beam are pivotally connected handles 12',said handles being suitably spaced apart and having the beam extendingbetween the inner ends thereof. A bolt 13 passing transversely throughthe beam and the handles provides the pivotal connection. By pivotmg thehandles as stated, it is possible to adjust them vertically to suit-theheight of the operator, and they'are held in adjusted position by a pairof brace bars 14 strad-' dling the rear end of the beam 10. The upperends of the brace bars are slotted as indicated at 15 and connected tothe handles by a bolt 16 passing therethrough and through the slots. Thebraces are connected intermediate their-ends to the sides ofthe beam bybolts 16 passing through the beam and through slots 17 in the braces.The lower ends of the braces carry-a supporting wheel 18 which isadjustable vertically to regulate the depth of the cultivation, thisadjustment being eifected by adjusting the braces. The slottedconnections shown enable the herein described adjustments to be readilymade, and the handles can be adjusted without disturbing the adjustmentof the supporting wheel, by simply loosening the bolt 16.

The implement is provided with ordinary spring teeth or shovels 19,which are carried by a-pair of transverse supporting bars 20 pivotallyconnected midway between their ends to the beam 10,'to swing in ahorizontal plane, by means of bolts 21. Five teeth are shown, two beinglocated on each side of the beam, and one at the center,'beneath thebeam, the pivot bolts 21 passing through the shank of said center tooth.The shank of each tooth is pivotally connected to both bars 20 bybolts22 so that, said bars may swing in parallel relation. The pivotalconnection between the bars 20 and the beam 10 enables the bars to beset to extend at right angles or obliquely with respectto the beam,

and the teeth are held in adjusted position by a brace 23 connected atone of its ends to the beam 10 and at its other end to one end of therear one of the bars 20. The brace is fastened by bolts 24, and has aseries of bolt holes 25 in order that it may be adjusted to suit theposition of the. bars 20. The bars 20 are adjustable to place the teethin position to work to the right or to the left.

The shank of each spring tooth 19 has an extra bolt hole 26, so that theteeth may be adjusted into different groups. Thus by moving the centertooth two holes forward, and the next tooth on each side thereof, one

hole forward, the teeth are grouped in the shape of a triangle, as shownin Fig. 4. By

letting the center tooth remain two holes forward, and moving the nexttooth on each side thereof back to its original place, and moving thetwo outside teeth one hole forward, the teeth are grouped as shown inFig. 5, a shape very desirable to cover guano, as the front tooth stirsup the same, and'the others, bytheir position, making a ridge on it. Byrunning over the ridge a week or fortnight later, the front toothmellows up the ground, and the other teeth form a ridge, which is verydesirable to plant cotton upon, or to set out strawberries.

By moving the bars one hole forward, the center tooth one hole backward,and the two outside teeth one hole forward, the teeth are grouped asshown in Fig. 6.

The teeth arranged in this manner will slide ed on the back tooth. Theteeth can also be set in various other positions, in view of which theimplement can be used for cultivating many different crops.

Fig. 3 shows a modification, a hand lever 27 being provided for shiftingthe bars 20 to place the same at different angles to the beam 10. Thishand lever is pivoted to one side of the beam,as indicated at 28 toswing in a vertical plane, and its upper end is within easy reach of theoperator.v The lower end of the lever is connected by a link 29 to therear one of the bars 20. The brace 23 will not be used with thisstructure, as the latter serves as a brace to hold the bars in adjustedposition.

By pulling the lever 27 rearward, the bars 20 are swung to extendobliquely across the beam 10 and the teeth 19 work right-handed. Whenthe lever is pushed forward, the bars are reversed and the teeth worklefthanded. The bars can also be adjusted to extend at right angles tothe beam; Suitable means 30 will be provided for locking the lever. Thehand lever and its connection can be removed and the brace 23substit-uted.

The last described adjusting means are designed primarily to be usedwhere the rows are narrow, so that reversing at each end of the rowleaves the furrow on the same side of each, and the middle is worked atone time. Where the rows are wider, and it is desired to go over thesame twice or oftener, the first-described structure is more practicalas it is lighter and possesses greater rigidity.

I claim 1. The combination of a beam, a pair of parallel cross-barspivoted intermediate their ends to the beam to swing in a horizontalplane, and extending from opposite sides of the beam, cultivator teeth,and pivot bolts passing through the bars and the shanks of thecultivator teeth, said shanks having a plurality of bolt holes to permitadjustment of the teeth horizontally relative to one another forward orrearward of the bars to vary the grouping of the teeth.

2. The combination of a beam, a pair of parallel cross-bars pivotedintermediate their ends to the beam to swing in a horizontal plane, andextending from opposite sides of the beam, cultivator teeth, pivot boltspassing through the bars and the shanks of the cultivator teeth, saidshanks having a plurality of bolt holes to permit adjustment of theteeth horizontally relative to one another forward or rearward of thebars to vary the grouping of the teeth, and a tooth mounted beneath thebeam and adjustable horizontally in the direction of the length thereofrelative to the other teeth.

In testimony whereof I aflix my signature in presence of two witnesses.
